THOMAS UTLEY, OF LIVERPOOL, ENGLAND.

SHIPS LIG'HT AND'AlR-PORT.

SPECIFICATION forming part of Letters Patent No. 539,315, dated. May 14, 1895. Application filed December 18, 1894. $erial No. 532,225. I (No model.)

To crZZ whom it may concern.-

Be it known that I, THOMAS UTLEY, engineer, a subject of the Queen of Great Britain, residing at Sefton House, Crosby Green, West Derby, Liverpool, in the county of Lancaster, England, have invented certain new and useful Improvements in Ships Lights and Ports, of which the following is a specification, reference being had to the accompanying drawings.

My invention relates to ships side lights.

According to my invention I provide the glass holder with pivot pins about which it can be turned when desired into a position approximately at right angles to the ships side. The said pivot pins are received in grooves or channels in the fixed casing of the side light and can slide therein to allow of the turning of the glass holder. The fixed frame is formed with an internal flange at its inner end to receive the packing ring against which the glass-holder bears when closed. In the said flangewhen applied to a rectangular side light, are gaps closed by hinged closing pieces as and for a purpose hereinafter fully explained.

An important feature of my invention is the attachment of the screw-retaining bolts to the glass holder.

In the accompanying drawings, Figure 1 is an elevation from inside the vessel of a rectangular side light constructed according to my invention. Fig. 2 is a horizontal section on the line w as, Fig. 1. Fig. 3 is a horizontal section showing an intermediate position of the glass-holder when opening. Fig. 4 is a vertical section on the line y y, Fig. 1, showing a channelhereinafter described. Fig. 5 is an ceive the usual packing or jointing ring A for making a water-tight joint between the casin g and the glass-holder. The latter is furnished with a projecting rim B to bear againt the aforesaid packing ring when the side light is closed.

The glass-holder is provided at top and bottom with pivot pins B B whichare received and can slide in grooves or channels A A provided in the fixed casing A. The said grooves or channels extend in a direction at right angles to the ships side, so-that when the retaining screws D, D D, D which are hinged to the glass-holder are unfastened and disengaged from the jaws of the fixed casing the said glass-holder can be moved bodily outboard to the position shown in Fig. 3, that is to say, until the pivot pins arrive at the ends of the channels. The side-light can then be turned about its pivot pins into a position at right angles to the ships'side. An intermediate position of the glass-holder while turning is shown by dotted lines in the said figure.

The retaining bolts or screws are as above indicated hinged to the glass-holder and can engage with jaws on the fixed frame. When the nuts of the retaining bolts are screwed up the rim B of the glass-holder is pressed very tightly against the packing ring A and a perfectly water tight joint is'thereby insured. If a sea strikes the glass it serves merely to increase the pressure of the holder against the flange and so'makes the joint more tight.

In order that the glass-holder may not when open project outboard too far I provide for allowing it to be drawn inboard, as follows,

that is to say, I provide a gap A in the top and also in the bottom of the flange A of the casin g in line with the pivot pins of the glassholder, and I close said gaps by pieces A A which are hinged to the casing. A, Name the hinge pins of the said pieces. The jaws A with which the top and bottom screw-retaining bolts D engage are formed on the said pieces A so that when the side light is closed and screwed home tight by its bolts D the pieces A are kept tightly pressed against the part A of the fixed casing. When the bolts D are unscrewed to open the side light, these pieces A A can be turned back and the glassholder can then be drawn inboard through the gaps A in the flange A.

In some instances the fixed frame of the rectangular light is made so deep (the grooves or channels being correspondingly length-- ened) that the glass-holder will turn without hinderance and without projecting outboard too far, and in such a case it becomes unnecessary to provide the gaps and closing pieces in the flange.

My improved construction of side-light may obviously be applied to those lights that have a ventilator in the fixed frame.

The side light shown in Fig. 5 is circular,

and is pivoted at top and bottom in channels in the fixed frame in the same manner as the rectangular light above described. It is shown with two retaining bolts D, D, but it may have four such bolts if desired. With a circular light it is not necessary to provide gaps in the flange of the fixed frame to allow the glass-holder to be drawn in board when turned at right angles to the ships side as is the case with the rectangular light.

What I claim is- 1. In a ships side light the combination of an inwardly flanged fixed frame, a jointing ring in the flange, a glass holder furnished with pivot pins, guide channels in the fixed frame to receive the said pivot pins, and screw retaining bolts hinged to the glassholder and engaging with jaws on the fixed frame, substantially as described.

2. In a ships side light the combination of an inwardly flanged fixed frame, a jointing ring in the flange a glass-holder furnished with pivot pins, guide channels in the fixed frame to receive the said pivot pins, screw retaining bolts hinged to the glass-holder and engaging with jaws on the fixed frame,anda rim on the glass-holder to bear against the jointing ring when the light is closed, substantially as described.

3. In a ships side light the combination of an inwardly flanged fixed frame, a jointing ring in the flange, a glass holder furnished with pivot pins, guide channels in the fixed frame to receive the said pivot pins, and removable portions in the flange to admit of the projection of the glass-holder through the frame when turned at right angles thereto, substantially as described.

4. In a ships side light, the combination of an inwardly flanged fixed frame, a jointing ring in the flange, a glass-holder furnished with pivot pins, and with screw retaining bolts, guide channels in the fixed frame to receive the said pivot pins, gaps in the flange opposite the pivot pins, hinged pieces to fill said gaps and thus complete the flange, and jaws on said hinged pieces to engage with the screw retaining bolts of the glass-holder, substantially as described, and for the purpose specified.

In testimony whereof I have hereunto set my hand this 7th day of December, 1894.

THOMAS UTLILY.
